6 Claims.

My invention relates to new and useful improvements in containers or receptacles such as paper cups or the like intended for but a single use and adapted to be nested in stack-formation so that the terminal container or receptacle" may be withdrawn for use and the principal object of the present invention resides in the formation of the receptacles or containers so that when nested the stack will remain straight and the containers or receptacles will not have a tendency to twist or turn out of alignment.

A further object of the invention resides in the method of arranging the containers or receptacles in the stack, the overlapping side seams of alternate containers or receptacles being folded and extended in opposite directions.

A still further object of the invention resides in forming two separate sets of the containers or receptacles from blanks of the same formation or configuration, the blanks being initially positioned so that they may be formed into the individual containers or receptacles of the sets with the individual receptacles or containers of one set having their sealing flanges folded and extending in opposite directions from the sealing flanges of the individual receptacles or containers of the other set, the completed individual receptacles or containers being finally nested into stack formation with the individual receptacles or containers of one set alternating with the individual receptacles or containers of the other set.

With the above and other objects in view, which will appear as the description proceeds, my invention consists in the novel details of construction and arrangement of parts described in the following specification and illustrated in the accompanying drawing, and while I have illustrated and described the preferred embodiments of the invention, as they now appear to me, it will be.

In the drawing: Fig. 1 is an elevation of a stack of nested receptacles.

Fig. 2 is. an elevation showing the receptacles of a stack partially separated.

Fig. 3 is aplan showing the position of a blank from which the receptacle shown in Fig. 4 is folded or formed.

folded from the blank shown in Fig. 3.

Fig. 5 is a plan showing the position of a blank Fig. 6 is an elevation of a receptacle formed or folded from the blank shown in Fig. 5; and

Fig. 7 is a perspective of a completed receptacle.

In the drawing a and b indicate blanks of the material, preferably paper, from which the receptacles or cups are adapted to be formed or foldrected'sectors or keystone-shaped portions 1 and 2, a flange or extension 3 being formed on one longitudinal edge of the portion 1 while a flange or extension 4 is formed on the opposite longitudinal edge of the portion 2. In forming the receptacles or cups the blanks are adapted to be initially folded on the transverse or horizontal center line and then the flanges 3 and 4 are folded to provide the overlapped side seams indicated generally at 5 and 6 in Fig. 7 of the drawing and extending inwardly over opposite faces of the receptacle or cup as shown more particularly in Figs. 4 and 6 of the drawing. When the individual receptacles or containers are completed it will be noted that they are of wedge shape with a substantially round normally open upper end and a relatively flat bottom closed edge as shown more particularly in Fig. '7 of the drawing and with this formation the receptacles or containers may be readily stacked as shown moreparticularly in Figs. 1 and 2 of the drawing with the receptacles or containers nested one within the other and adapting the terminal receptacle to be readily removed. The completed individual receptacles or containers nested in the stack, are indicated at '1.

By reference more particularly to Figs. 4 and 7 of the drawing it will be seen that the overlapped side seams 5 and 6 formed by the flanges 3 and 4 are folded and extend in a direction opposite to that shown in Fig. 6 and this manner of folding and extending the flanges which form the side seams or seals permits the receptaclesor containers to be evenly stacked, as shown more particularly in Fig. 1 of the drawing and prevents the same from turning or twisting in the stack. In other words if the flanges forming the Fig. 4 is an elevation of a receptacle formed or side seams or seals of the individual receptacles or containers were folded and extended in the same direction, it has been found, in actual practice, that as they are nested into stack formation that they will have a tendency to twist or turn.

From the above it will be seen that the receptacles or containers shown in Figs. 4 and 6 of the drawing are made from blanks of material of the same shape or configuration and the blanks for forming the containers or receptacles illustrated in these figures of the drawing are merely placed in difierent positions as shown in Figs. 3 and 5 of the drawing beforefolding or forming. Two separate and distinct sets of individual receptacles or containers are provided, one set being formed from the 'blanks positioned as shown in Fig. 3 and the other set being formed from the blanks positioned as shown in Fig. 5; As previously stated the individual containers or receptacles of one set have their side seams or seals folded and extended inadirectionopposite to that of the individual containers or receptacles of the other set and in nesting the receptacles or containers into the stack formation the individual receptacles or containers of one set are alternated with the individual containers or receptacles of the other set and this arrangement of the nested receptacles or containers prevents them from turning or twisting in the stack such as would be the case if the side seams or seals of all of the individual containers or receptacles were folded and extended in the same direction.

Having fully described my invention what I claim as new and desire to secure by Letters Patent is:-

1. The method of forming and stacking individual normally open mouth receptacles which consists in initially forming two sets of the individual receptacles with the side seams of the receptacles of one set folded and extended in opposite directions to the side seams of the receptacles of the other set, and then nesting the receptacles into stacked formation, the receptacles of one set alternating with the receptacles of the other set.

2. The method of forming and stacking individual normally open mouth receptacles which consists in initially providing blanks of similar formation or configuration and then positioning them so that they may beformed into two distinct sets of individual normally open mouth receptacles, the individual receptacles of one set having sealing flanges folded and extended in opposite directions from sealing flanges of the individual receptacles 01' the other set, and finally nesting the receptacles into stacked formation, the individual receptacles of one set alternating with the individual receptacles of the other set.

3. The method of forming and stacking individual normally open mouth receptacles which consists in initially forming two sets of individual receptacles with their-side seams folded to extend over opposed faces, the side seams of one set being folded in opposite directions to the side seams of the other set, and then nesting the receptacles into stacked formation, the receptacles of one set alternating with the receptacles of the other set.

4. A stack of normally open mouth receptacles in which individual receptacles of two sets of receptacles are arranged alternately, the individual receptacles of one set having overlapped seams folded and extended in opposite directions to the overlapped seams of the individual receptacles of the other set.

5 A stack of wedge-shaped normally open mouth receptacles in which individual receptacles of two sets of receptacles are arranged alternately, the individual receptacles of one set having overlapped side seams folded and extended in opposite directions to the overlapped side seams of the individual receptacles of the other set.

6. The method of stacking normally open mouth receptacles which consists in nesting individual receptacles of two sets of receptaclesalternately, the individual receptacles of one-set having overlapped seams folded and extended in opposite directions to the overlapped seams of the individual receptacles of the other set.
